What does it mean that God is the difference maker in salvation?

In the context of sovereign grace theology, when we say that God is the difference maker, we are affirming that all aspects of salvation are the result of God's sovereign action. This encompasses God’s choice to save, the calling of the elect, the work of Christ on the cross, and the application of redemption through the Holy Spirit. It is God who opens the hearts of the elect to believe the gospel, ensuring that they receive the faith necessary for salvation. This view emphasizes that our salvation is not contingent upon human effort or will but entirely rests on God's power and purpose. Thus, the glory of salvation belongs solely to Him, the one who transforms hearts and lives for His own glory.
